- `fn name` names a top-level function as a value (E_FNREF, lowers to @fn_<name>); the worker entry point for Job.parallel_for, which checks it takes (int, pointer-like) and returns void. - runtime/native/threads.ll (pthreads) and threads_win.ll (Win32 SRWLOCK/CONDITION_VARIABLE): a pool of one worker per core but one, parked between batches; every thread claims chunks by compare-and-swap. Linked only into programs that use Job/Promise/Sync, by `ludicc -o`, `ludic build` and the test suite's build helper. - Sync.* is real: native mutexes, atomics as cmpxchg retry loops (neither clang takes atomicrw, the PC's rejects seq_consistent), mutex-guarded channels, Sync.cpu_count from the OS. - spawn/despawn on a pool thread stop the program with a located panic. - examples/library/threads.ludic and its test; docs for fn, Job.parallel_for, Job.is_worker. - Reseeded (bootstrap-cfree: out.ll == seed.ll). 141/141 on macOS; jobs, threads and the guard pass on Windows from the reseeded Windows seed.

| job-is_worker | Job.is_worker | job | namespace-method | Job.is_worker | Job.is_worker() -> bool | True on a Job.parallel_for pool thread, false on the main thread. | 17 | Job | is_worker |
True when the code is running on a Job.parallel_for pool thread, false on the main thread (and on
the calling thread while it takes its own share of a batch).
if not Job.is_worker() { print("main thread") }
